Table REF  shows that GraphTrailer with TPs
provides on average more informative (Q1) and attractive (Q2) trailers
than all other systems. Although GraphTrailer without TPs and
Supervised GraphTrailer are more often selected as best, they are
also chosen equally often as worst. When we compute standardized
scores (z-scores) using best-worst scaling [1]}, GraphTrailer with TPs
achieves the best performance (note that is also rarely selected as
worst) followed by Supervised GraphTrailer. Interestingly,
GraphTrailer without TPs is most often selected as best (24.40%),
which suggests that the overall approach of modeling movies as graphs
and performing random walks instead of individually selecting shots
helps create coherent trailers. However, the same model is also most
often selected as worst, which shows that this naive approach on its
own cannot guarantee good-quality trailers.
